HUMIDIFYING DEVICE- Specification of Letters Patent.

' To all whom it may concern.-

Be it known that I, OHARLEs M. OoLvIN, a

j citizen of the United States of America, and a resident of Wilmette,in the county of Cook and State of Illinois, have invented certain newand useful Improvements inHumidif ing Devices, of which the following isa specification.

The main objects of this invention are to provide an improved device forimpregnating the air with moisture, controlling the ,amount of moisture,preventing the dis charge of spray from the apparatus, driving suchimpregnated air a comparatively long distance from the apparatus, anddriving such impregnated air in anydesired direcdinal section of adevice constructed accordmg to this invention.

In the device shown, 1 is acylinder open 4 at each end and havingsecurely mounted therein at its rear end the electric fan 2. Asteam-pipe 3' extends into the cylinder 1 and has its upper end providedwith a cap 4, having therein an opening 5, through which the steam isdischarged against the rear wall 6 of the hood or protecting-chamber 7.The

a chamber 7 has an opening 8 located opposite and on a line with thecenter of the fan 2. The protecting-chamber 7 is supported on thedrain-pipe 9, which is secured in the wall of the cylinder 1 and in thebushing 10. The

, lower wall of the protecting-chamber 7 is apertured at 11 to permitthe condensation from the steam to fiow into the drain-pipe 9.

The bushing 1 0 is j ournaled in the supportingi'rame 12. The waterdripping through the drain-pipe 9 may be carried away by any suitableconveyer or receptacle, whichmay be located under the frame 12. wires 13leading-to the motor 14 of the fan are made flexible and of suflicientlength to permit the cylinder 1 to be turned to any desired position onits bearing in the frame 12. The form of device shown is intended to beused at one end of a room for throwing the moistened air toward theopposite end or toward either side of the room, and is particularlyadapted for use in large warehouserooms for keeping in storage tobaccoand other materials which it is desired to keep 1 wall and through theaperture 11.

ferred position of the device is that shown in The conductor-'impregnated with a certain amount of moisture, but which would be rottedor otherwise injured if kept in an atmosphere of too high humidity or ifsubjected to a spray.

The operation-of the device is as follows: The flow of steam iscontrolled by the valve 15 and is permitted to flow through the aperture5 against the wall 6 of the protecting pipe 3 will gather in the chamber7' and be carried away through the drainpipe 9. ;The end 16 of thechamber 7 prevents the water from the condensed steam from flowingchamber 5. The condensation from the through that end of the chamber,but permits the steam to pass out into the air-passage or cylinder 1through the aperture 8. The operation of the fan 2 causes a current ofair through the cylinder 1 in the direction of the arrow and helps todraw the steam out of the aperture 8. The action ofthe fan causes acurrent of air through the cylinder, which thoroughly mixes with thesteam passing out of the protector 7 and blows the mixture a longdistance from the apparatus.

The object of having the ipe 3 provided with a cap opening toward t erear is to prevent the steam from being blown directly The amount ofmoisture with which the air is imvpregnated will be regulated by thevalve15.

from the pipeS toward the aperture 8, and

thus prevents the carrying of spray out of the aperture 8. When thecylinder 1 is turned toward either side, the aperture 5, in

the form shown, will discharge toward one of the side walls of theprotecting-chamber 7, causing the condensation to flow down suchThe.pre-

the drawing. If the cylinder is turned in the opposite direction, thenthe cap 4 may be li :ewise turned on its threaded .seat so as todischarge in a direction away from the discharge of the cylinder 1. j i

What I claim as my invention, and desire to secure by Letters Patent, is

1. A humidifying apparatus comprising a passage for the air to betreated, a steampi e discharging into said passage, means or forcing theair to be treated through said passage, and a protecting chamber or hoodover said steam-pipe, having a steam-opening into said passage butadapted to prevent the drip from the condensed steam from being carriedinto said passage.

2. A humidifying apparatus comprising a passage for the air to betreated, a steampipe discharging into said passage, means for forcingthe air to be treated through said. passage, and a protecting chamber orhood over said steam-pipe, having a steam-opening into said passage, butadapted to prevent the drip from the condensed steam from being carriedinto said passage, said steam-pipe being adapted to discharge into saidchamber in a direction away from the opening in said pro. tector.

3. A humidifying apparatus comprising means for inducing a current ofair, a protecting-chamber open in the direction of said current andclosed in the opposite direction, and a steam-pipe discharging into saidchamber in a direction away from such opening,

and a passage inde endent of said opening for carrying the drip omthe'condensed steam out of said chamber.

4. A humidifying apparatus comprising an outer casing having an openingfor receiv ing air at one end and an opening for discharging air at theother end, an inner casing open toward the discharge end and closedtoward the receiving end, a steam-pipe discharging into said innercasing, and means for inducing a current of air through said outercasing.

5. A humidifying apparatus comprising an outer casing having an openingfor receiving air at one end and an opening for discharging a current ofair at the other end, an inner casing open toward the discharge end andclosed toward the receiving end, a steampipe discharging into said innercasing, a passage, independent of said opening of the. inner casing, forcarrying the drip from the condensed steam to the outside of the outercasing without contact with said current of air, and means for inducingthe current of air throu h said outer casing.

6. li n a humidifying apparatus, a supporting-frame, an outer casingjournaled thereon and having a receiving-opening and adischarge-opening, an inner casing open in the direction of saiddischarge opening and closed in the direction of said receiving-opening,a steam-pipe discharging into the inner casing, and means located insaid outer casing for inducing a current of air through the same.

7. A humidi'l'ying apparatus comprising.

means for inducing a current of air, a protecting-cl1amber being open inthe direction of such current and closed in the opposite direction, anda steam-pipe extending into said casing and having its inner endterminating free from the walls thereof.

8. A humidifying apparatus comprising means for inducing a current ofair, a protecting-chamber being open in the direction of such currentand closed in the opposite direction, and a steam-pipe extending intosaid casing and having its inner end terminating free from the wallsthereof, and discharging in a direction away from the opening in saidcasing.

9. A humidii'ying apparatus comprising means for inducing a current ofair, a protecting-chamber being open in the direction. of such currentand closed in the opposite direction, a steam-pipe extending into saidcasing and having its inner end terminating free from the walls thereof,and means for catching the drip from the condensed steam andv preventingthe same from being carried into said current of air.

1 O. A humidiiying apparatus comprising an outer casing open at oppositeends, means for inducing a current of air through said casing, an innercasing open in the, direction of said current of air and closed in theopposite direction, a steam-pipe extending into said inner casing anddischargin in a direction away from the opening therein, and means forpreventing the drip from the condensed steam from being deposited uponthe inside of the walls of the outer casing.

11. A humidii'ying device comprising means for inducing a current ofair, a protecting-casing open in the direction of said current andclosed in the opposite direction, having its bottom wall slopingdownwardly away from said opening, a drip-pipe communicating with saidcasing for carrying the drip away from said opening and said current,and a steam-pipe discharging into said casing in a direction away fromsaid opening.
